双Higgs双重态模型III中轻子味破坏$τ^- \to μ^- PP$衰变

Lepton Flavor Violating $τ^- \to μ^- PP$ Decays in the Two Higgs Doublet Model III

Wenjun Li, YingYing Fan, Gongwei Liu

摘要:

本文在双Higgs二重态模型(2HDM)III的框架下研究了轻子味破坏$τ^- \to μ^-PP (PP=K^+K^-,K^0\bar{K}^0,π^+π^-,π^0π^0)$衰变。我们计算了这些衰变的分支比,并由实验上限得到了模型参数$|λ_{τμ}|$的界。结果表明,中性希格斯玻色子玻色子对这些衰变有树能级贡献.在这些衰变中,$τ^- \to μ^- K^+K^-$衰变对$|λ_{τμ}|$最敏感。在现有的参数空间中,这些衰减可以达到B工厂的测量能力。这些过程可以为未来的研究提供一些有价值的信息,并为验证2HDM III模型提供可靠的证据。

英文摘要:

In this paper, the lepton flavor violating $τ^- \to μ^-PP (PP=K^+K^-,K^0\bar{K}^0,π^+π^-,π^0π^0)$ decays are studied in the framework of the two Higgs doublet model(2HDM) III. We calculate these decays branching ratios and get the bounds of model parameter $|λ_{τμ}|$ from the experimental upper limits. Our results show that, the neutral Higgs bosons have tree-level contributions to these decays. Among these decays, the $τ^- \to μ^- K^+K^-$ decay is most sensitive to $|λ_{τμ}|$. In the existing parameters space, these decays could reach the measure capability of B factory. These processes can provide some valuable information to future research and furthermore present the reliable evidence to test the 2HDM III model.
